Trusted Data Storage Architecture for National Infrastructure

Abstract

National infrastructure is a material engineering facility that provides public services for social production and residents’ lives, and a large-scale complex device or system is used to ensure normal social and economic activities. Due to the problems of difficult data collection, long project period, complex data, poor security, difficult traceability and data intercommunication, the archives management of most national infrastructure is still in the pre-information era. To solve these problems, this paper proposes a trusted data storage architecture for national infrastructure based on blockchain. This consists of real-time collection of national infrastructure construction data through sensors and other Internet of Things devices, conversion of heterogeneous data source data into a unified format according to specific business flows, and timely storage of data in the blockchain to ensure data security and persistence. Knowledge extraction of data stored in the chain and the data of multiple regions or fields are jointly modeled through federal learning. The parameters and results are stored in the chain, and the information of each node is shared to solve the problem of data intercommunication.

Operating system network security enhancement scheme based on trusted storage

“…Performance is greatly improved compared to traditional host-based trusted computing approaches. Han et al [14] proposes a trusted certificateless authenticated public-key encryption with keyword search scheme (TCA-PEKS) using keyword search in cloud storage, and constructs an open and transparent smart contract to limit the malicious behavior of ECS and ensure trusted retrieval. Wang et al [15] proposed a blockchain based trusted data storage architecture for national infrastructure, which solves the problem of data interoperability through the Internet of Things (IoT) and federated learning technology.…”
